LM5119 Overview
The LM5119 is a dual synchronous buck controller intended for step-down regulator applications from a high voltage or widely varying input supply. The control method is based upon current mode control utilizing an emulated current ramp. Current mode control provides inherent line feed-forward, cycle-by-cycle current limiting and ease of loop pensation.
LM5119 Key Features
- Emulated peak current mode control
- Wide operating range from 5.5V to 65V
- Easily configurable for dual outputs or interleaved single
- output Robust 3.3A peak gate drive Switching frequency programmable to 750kHz Optional diode emulation mode Programmable
